Wickman is pretty much healed. His velocity is back. Isringhausen is a concern, but Urbina should be fine. With a 20 save lead, this trade looks good.

Green is so streaky that he's frustrating to own. Johnson is back to old form after a month long struggle (even though he was still a top pitcher over the last month!).

I think I would go for it. Especially since you feel you don't need Green. Comparing Green for Morris to Green/Smoltz for Johnson, based on your team, I would go for Johnson. Morris is great, but he's no Unit.
